Android: How to remove old references in R.java?

I am new to Android and I don't know much about Android. Well I have created a layout named button-layout.xml and the very firstly I added a relative layout to and and named it too button-layout.

What happens is that it created R.java and crated a reference to my layout with name public static final int button-layout=0x7f060000; as you people know that you can not use - in your variable name as it is illegal.

Now I want to clean my R.java do any body knows solution of this problem?

Pasting my code below button-layout.xml

    <?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/button-layout">
    <LinearLayout android:id="@+id/button-layout"
        android:layout_height="wrap_content" android:layout_width="fill_parent">
        <TextView android:id="@+id/TextView01"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="First Name"></TextView>

    </LinearLayout>
    <LinearLayout android:id="@+id/LinearLayout02"
        android:layout_below="@id/LinearLayout01" android:layout_width="wrap_content"
        android:layout_height="wrap_content">

            android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Last Name"></TextView>
        <EditText android:id="@+id/EditText02"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:width="100px"></EditText>
    </LinearLayout>
    <LinearLayout android:id="@+id/LinearLayout03"
        android:layout_below="@id/LinearLayout02" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_centerInParent="true">
        <Button android:id="@+id/Button01"
            android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Submit"></Button>
    </LinearLayout>
</RelativeLayout>

The R.java file is automatically generated by resource compiler (AAPT). So every time you make changes to your project, and save, the R.java file is rebuilt.

R.java is rebuilt again when you Build your project, incase it doesn't delete it and re-built....
